There is a crest high out of a window. go to the Quidditch Training Grounds, walk up the steps to the guy in the portrait whose password is "Boiled Beatles" keep walking up, and then look out of the windows you will see a crest. you need to walk down the steps to get something to knock it down--the flower pot things.

You pick up the lever and hit it into a wall. Then you pick up the pieces, get them through the gate, use Reparo on the lever and open the gate.

A2:

The lever pieces are nearby the gate and what you do is use "Wingardium Leviosa" to move the object through the gate. Then you use "Reparo" to repair it and finally, just put the lever in the slot and the gate will open.

I have the same problem! I saw a video on youtube, but nothing... you can see it and tell me if you can find something... See the video: Answer Video -Answer by:PH91

I'm afraid EA didn't want to put Two-Dueling mode.Castle gates is a 2-player dueling area.You can put the code on a PS3 XBOX 360 or Wii and maybe the little PS2.Sad face.PC does not have 2 player mode.Hope the next game will have. -Answer by:razvan89

There are three saved games --- they are called profiles
kind of confusing if you have done it under the same name
also if you play around a bit you can get an autosave rather than a save and get out of a story mission and go back to open world. -Answer by:saboteurmaster

You are half right... You do need to cast W.L. on nearby objects, but then stand still, aim (so that you are facing the crest directly) and depulso (up twice) to throw the object at it :o) -Answer by:mikeyboy235

I found out this cheat by accidentally pressing a key during the came and it has helped me tremendously and now I want to share it.

Do you ever get it that no matter how hard you try to nock down a crest it just wont budge? Well follow this step-by-step cheat and it will become allot easier to do.

1- Find the crest you want to nock down.

2- Cast Wingardium Leviosa on the object you want to use to nock it down. (This object can be anywhere. It does not have to be in throwing range of the crest. It doesn't even have to be in the same room as the crest. I would recommend using either a Dung-bomb or an Exploding Cauldron but its up to you)

3- Once the object is in the air hold down the SHIFT key. (The one that looks like an arrow pointing up. The same key that you use to run fast.)

4- You are now free to walk about the castle and grounds, still carrying the object in the air. Make sure that you keep the SHIFT key down until you get to where the crest is. (During this time the SHIFT key will not make Harry fun fast)

5- Now throw that object at the crest to nock it down.

I found this very helpful, as I would get frustrated when I was unable to nock a crest down with a rock or an ornament. I found it easier to use Dung-bombs and Exploding Cauldrons but there would never be any close enough. So I would just carry one from another area.

Hope this helped =D

NOTE- I do not know if this cheat will work on other platforms as-well like PS3 or Xbox but you can try

I had a lot of trouble getting the crest on the high quidditch tower. Lots of websites say to use the flower pot from further down the staircase but I tried that so many times and it never works. Finally I used the bench from the steps below - levitated it up to the tower with the flower pot in it, perched it on the stairs, went back up and threw it up to the crest - it finally worked!
